PAUL DICKINSON, OF CHICAGO, ILLINOIS.

SMOKE-STACK.

To all whom it may concern.-

2 Be it known that I, PAUL DICKINSON, a citizen of theUnited States, residing at Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement in Smoke-Stacks, of which the following is a specification.

My invention relates to'improvement in the construction of smoke-stacks for enginehouses or roundhouses, as they are generally called, in which locomotives are temporarily stored.

It is usual to provide a smoke-stack over each of' the locomotive-stalls in an enginehouse, with which stack the stack ofa 1000- motive may register when it enters a stall, whereby the smoke and gases from the locomotive are conducted directly through the 'roof without'contaminating the air in the building. Itis also usual to equip such buildings with machines, tools, and appliances useful in making repairs upon locomotives while in their stalls.

My object isto provide a smoke-stack of the above class and supporting means therefor of improved construction whereby thesmoke-stack may be readily moved longitudinally of the stall to position it with relation to the stack of a locomotive and whereby a traveling crane may be supported to move above the locomotive-stalls.

In the accompanying drawings, showing a desirable embodiment of my invention, Figure 1 is a broken vertical section of a roundhouse at one of its locomotive-stalls; Fig. 2, a sec:

tion taken on line 2 in Fig. 1; Fig. 3, a broken plan section taken on line 3 in Fig. 2 with the roof of the roundhouse left out to disclose features which would otherwise be hidden and showing the track, carried by the. sliding monitor-roof, by dotted lines; Fig. 4, a broken sectiontaken in a plane parallelto Fig. 1 and illustrating the means for moving the smokestack longitudinally of the stall; Fig. 5, a broken sectional view in-the same plane as Fig. 4 and illustrating the means for raising and lowering the smoke-stack; Fig. 6, an enlarged broken View, in side elevation, of the smoke-stack raising, lowering, and positioning gears and means for throwing an obstacle 'or guard into and out of the pathof the traveling crane; Fig. 7, the guardand its operating mechanism in another position; Fig. 8, a broken elevation of the opposite side of the mechanism shown in Fig. 6; Fig.

raising, lowering, and positioning mechanism; Fig. 10, a broken plan section taken just above the plane of the traveling'crane; and Fig. 11, a diagrammatic illustration in perspective, showing the smoke-stack and means for moving the same and raising and lowering its telescoping sections.

A is the wall of an engine-house or roundhouse, and B the roof thereof. Intheroof B centrally over the tracks of the stall is an opening a, leading to a monitor, forming part of the roof structure and having stationary side walls 6 b and stationary end walls 0 Q.

.Mounted in brackets d on the walls 6 are grooved wheels 0, which are all in the same horizontal plane close to the tops of the said walls.

C is a movable monitor roof or cover, formed with side strips ff and end strips 9 g. The cover Cv may be'of a length approximating twice that of the opening a and carries a pairof parallel longitudinally-extending rails it h, which the wheels 0.

D is a smoke-stack formed with a top secengage and ride'upon tion '11, rigidly mounted in the center of the movable cover or monitor-roof C. The lower end of the upper section dis reinforced and flanged, and extending through the said flange is a pin or bolt Z4, on which is pivotally mounted the section Z of the smoke-stack D. Telescoping into the section Z is a next lower section 110, and telescoping into the section 272 is the lowermost section 10, adapted to be brought into operative relation with the stack X of a locomotive in the stall. The roof C is watertight around the smoke-stack section 11, and

the said roof carrying the stack is supported altogether by the rails 72,, which slide uponthe wheels 6. The side strips f and endstrips g of the monitor-roof extend downward below the plane of the top of the stationary sides and ends of the monitor, thereby preventing rain or snowfrom drifting into the monitor.

, E is one of a pair of parallel track-rails suitably supported, one by the wall A and the other (not shown) on a parallel support or opposite wall of the building; The track-rails E form guides and a support for the, wheels 10 of a traveling crane F. The crane is thus supported to move in a horizontal plane more or less below the roofof the building and above the plane to which a locomotive-stack X reaches. The. smoke-stack D, therefore, when in operative position extends across the path of the saidcrane. .Inorder that the tions of moving parts thereof.

crane may be moved from one stall to another in the building, it is necessary to provide means for moving the stacks out of the path of the crane to permit the latter to pass.

It has been found desirable for various reasons to provide roundhouses with smokestaeks which may be moved a more or less limited distance longitudinally of the stalls, so that a locomotive need not be stopped in any exact location to register at its stack with the said smoke-stack. Furthermore, while making repairs upon an engine in a roundhouse it is frequently desirable to move the locomotive a few feet to change the relative posi- By providing the roundhouse with a smoke-stack that may be shifted longitudinally of the stall the locomotive may be stopped in any location within a comparatively .wide range and the smokestaek above the stall be moved to conform to the location of the locomotive-stack. In the present construction the smoke-stack D may be moved a distance along the stall approximating the length of the opening a and monitor.

Journaled in a bracket-frame G on the wall A is a crank-shaft H or shaft provided with an operating crankhandle q, Fig. 9. The shaft H carries a pinion r, meshing with a gear-wheel s on a shaft I, journaled in the frame G. The shaft I carries a drum 6. A chain or cable '0, wound between its ends about the drum, extends from opposite sides there- 'of over pulleys 11 12. One length of the chain 4) extends from the pulley 12 under a pulley 13 and. over a pulley 14 and is fastened at its end to the pin or bolt 76 of the stack D. The other length o extends from the pulley 11 under a pulley 15 and over a pulley 1.6 to the pin or bolt 76, to which it is fastened at its end. The pulleys 11 to 16, inclusive, may be located as indicated in the figures, whereby when the drum 2, is turned by the shaft H in onedirection the chain or cable 1) draws the stack D and monitor-roof C toward one end of the monitor, and reverse motion of the shaft H causes the stack and monitor-roof to be moved in the other direction. On the shaft I is shown a ratchet-wheel 17 to be engaged by a swinging double pawl 18, whereby the drum t may be locked against turning in either direction to hold the stack firmly in any location of adjustment. This prevents the stack and monitor-roof from being shifted by a driving wind or from other cause.

The traveling crane moves in a plane above the locomotive-stack, and it is therefore necessary to provide a smoke-stack D of a construction which may be moved at its lower end a comparatively great distance in the vertical plane to permit the crane to pass. I have 7 found it desirable for this reason to form the lowering and raising part of the stack of a plurality of telescoping sections. Mounted on opposite sides of the lower end of the stacksection on are pulleys 19 19, and on opposite sides of the lower end of the section 12 are pulleys 2O 20. Chains 21 21 extend under the pulleys 19, thence over pulleys 22 45, and thence under pulleys 23 23 to opposite ends of a bar or frame 24, Figs. 3 and 11. Chains 25 extend beneath the pulleys 20 on the stackseetion n, thence over pulleys 26 and 27 and under pulleys 28 to opposite ends of a bar or frame 29. J ournaled in the bracket-frame G is a crank-shaft K or shaft carrying a crankhandle 30 and pinion 31. Also journaled in the bracket-frame Gr is a shaft L, carrying a gear-wheel 32, meshing with the pinion 31 and drums 33 34, one of much greater diameter than the other. A chain or cable 35, fastened at one end to the drum 33, extends over a pulley 36 and is fastened at its opposite end to the frame 24 between the ends of the latter. A chain 37, fastened at one end to the drum 34, passes over a pulley 38 and is fastened at its opposite end to the frame 29 between the ends of the latter. The pulleys over which the raising and lowering chains or cables for the smoke-stack extend are disposed as shown in the figures. The crank-shaft K, shaft L, and drums 33 34 form a graduated windlass which when turned in one direction causes the chain 35 to draw the frame 24 at one speed and the chain 37 to draw the frame 29 at a much greater speed. In thus moving the frame 29 draws the chains 25 to raise the stack-section a and the frame 24 draws the chains 21 to raise the stack-section m. The stack-section 12, rises much more quickly than the section 721, and the parts are preferably so constructed with relation to each other that when the stack-section m. is slid upward to the limit in the stack-section Z the stack-seetion a will be raised and telescoped into the section m to the limit. By means of the mechanism deseribedthe sections a we. may be raised very quickly out of the path of the crane F. In the construction of Windlass shown the shaft L carries a ratchet-wheel 39 to be engaged by a pawl 46 to hold the stacksections in adjusted position. When it is desired to lower the stack-sections, the shaft K is turned to unwind the chains 35 37, whereby the said stack-sections will descend by gravity.

To prevent danger of the traveling crane ever running into and doing injury to a lowered stack, I provide asafety appliance in the form of a swinging guard or block M, pivotally mounted in brackets 40 on the wall A at the side of the track-rail E shown. Journaled in the bracket-frame Gr above the shaft L is ashaft N, provided with agear-wheel 41, meshing with a pinion 42 on the shaft L. Extending nearly around the gear-wheel 41, coneentric with the shaft N, is a groove 43. A

or swinging block H.

the Windlass and gear-wheel41 is such that in the final turning of the Windlass to raise the stack-sections out of the path of the crane the end of the groove 43 engages and lifts the rod 44 to swing the block M out of the path of the crane. In the initial reverse movement of the Windlass to lower the stack-sections the said end of the groove 43 moves in the direction away from the end of the rod 44, permitting the latter to descend and the block M- to swing downward to the track-rail E. The block or guard M is of a length, as indicated in Fig. 10, to stop the truck or running-gear of the traveling crane before the latter can contact with the smoke-stack when moving thereto from either side.

Forming part of the'monitor-cover C is a base-plate w, which slides closely over the stationary end walls a and supports the trackrails 7L and the various chain or cable pulleys carried by the said cover.

While I have shown and described a convenient and desirable means for carrying'out the various features of my invention, details may be modified in many ways without departing from the spirit of my invention as set forth in the appended claims.

What I regard as new, and desire to secure .by Letters Patent, is
